Hey,

I use a Hungering Arrow build myself. It's my favourite build, just slight ahead of the auto attack build.
However with your build you are focussing only on strafe and Hungering Arrow. You can be much more effective though. You will get stunned lots of times by good teams, thus Strafe will be stopped and you are left with only Hungering Arrow.

If you want, try below build.
You already have 2 vaults and a stun with Rain of Vengeance, thus don't need Bolt of the Storm. Which can be changed for Nexus Frenzy. If you then change Frost Shot for Giant Killer, you will be effective with Hungering Arrow, Rain of Vengeance and auto attack.

You will win a 1 vs 1 against nearly everyone late game. Lay back in teamfights, do Rain of Vengeance and finish your enemy team with 3 deadly Hungering Arrows and it's game over for the other team.
